This invention relates to casting machines,

. particularly machines designed for casting flat, late-like objects such as grids for storage atteries, and the primary obg'ect is to provide a simple, efficient, and practical conveyer system that is so arranged with respect to the casting molds that it will receive the castings that are successively discharged therefrom, carry them'to a point remote from the molds and there stack them upon 'a table or shelf, from which theymay be carried or otherwise further conveyed to the cutting, trimming, and treating machines; The present application is a division of my co-pendin'g application, Sen-No. 301,830, filed August 24, 1928, for grid casting machine.

In the accompanying drawings:

Fig.1 is a side elevation of the lower por-.

tions of a grid casting machine, with various parts omitted, but showing a sufiicient number of arts to illustrate'the application and operatlon' of the conveyer system. For purpose of reference this may be considered the left side'of the machine, with the left end of the figure considered as the front.

Fig; 2 is a sectional plan view as on the irre ular line 2-2 in Fig. 1. I

*ig. 3 is an enlarged detail sectional ele- Referrin to the drawings more articularly and by reference characters, nates the base of thelead melting and fee ing mechanisms, saidbase' being" supported on legs 5and 6. The said melting and feeding mechanisms have been omitted, except that 7-d' "f 1' th h h'hth eslgnates eed es mug W 10 may be made in the structure as disclosed,

provided such modifications come within the molten etal is supplied to the molds. There are two. pair of molds, includingstationary 'moldsfB' arid-movable molds ,9. The stationamalgam secured-to a heavy castframe.

.1O," an t l eea eeuea totliis frame is a housing" 11 thatslidablytsupportsa pair of reciprocating rains '12-Jca1frying-the movable molds 9.

Forpresentgplirposesit is sufficient to state that the molds a"re-intermittentlyv opened and closed, thata-predeterminedcharge of mol ten metaliisjs'upplied to the molds, when closed, by the nozzle ,7,- and, that after such metal has hardened the, moldsopen to disa melting and charge the castings 13 which drop under the influence of ravity.

' As the cast ngs 13 are successively released from the molds 89 they fall into sliding contact with a receiving plate 14. This plate is secured to and within the framework 10 and is so curved and inclined that it will receive and direct the castings downwardly and forwardly, discharging them, at its lower end, upon the lower rearpart of an inclined endless conveyer belt 15 carried by a frame 16 secured to the legs 5'-6.

The upper conveyer roller 17 has, a sprocket pinion 18, driven from a sprocket pinion 19, by a chain 20. -The pinion 19 carries a worm gear 21 meshing with the worm 22 of a shaft 23, driven by the motor 24. Slack in the belt 15 may be takenup by set screws 1 25, and the proper tautness in the chain 20 is had by moving the gear support block 26 has received a certain number of plates they may be temporarily piled upon a larger shelf 1 '30 until they are to be carried away or delivered to the cutting or trimming machine.

The shelf 29 is preferably adjustably se-'. cured 'to, the upper ends of the conveyer frame bars 16, so that-it may be set to the most advantageous position for properl'yre-j ceiving and stacking the grid plates 13.

It 1s understood that suitable modifications spirit and "scope of the appended claims. Having now therefore fully illustrated and described my invention, what I claim to be i new. and desire to protect by Letters Patentis:

1. In a casting machine having a base for eedin mechanism, a mold unit at one side of, the ase, a support at the opposite sideof'thebase'from the mold unit, and a conveyer for conveying castings from the mold unit to the support. 7

2; Ina casting mach' '0' having a base for a melting and feeding mechanism, a mold unit at one side of the base, a support at the opposite side of the base from the mold unit, and a conveyer extending under the base for 6 transferring castings from the mold unit to the support.

3. In a casting machine having a base for a melting and feeding mechanism, a mold unit at one side of the base, and a eonveyer 10 extending under the base to transfer castings from the casting unit to the other side of the base therefrom.

4. Ina casting machine having a base for a melting and feeding mechanism, a mold 15 unit at one side of the base, a stacking shelf at the opposite side of the base from the mold unit, a chute extending downwardly from the molds of the mold unit to a point adjacent said base, and an inclined conveyer 20 having its lower end disposed adjacent to the lower end of the chute and extending under said base with its upper end disposed adacent to the stacking shelf so as to deliver the castings in a horizontal position thereto. 25 Signed at Minneapolis, in the county of Hennepin and State of Minnesota, this 15th day of August, 1929. i
